TO ALL WHOM IT MAY CONCERN:

Be it known thBLt I,WIELIAM FUZZARD, of Chelsea, in the county of Suffolk, and State of Massachusetts, haveinvented a new and useful improvement in Machines for Surface Sizing Fibrous Materials; and I do hereby declare that the following is a full, clear, and exact description thereof, which willenable others skilled in the art tomalreand'use thesa'me, reference being had tothe accompanying drawing=, forming part of this specification, in which-. -Q t o p i Figure 1 is a side sectional viewof my improvement, taken in the line a; ayfig. 2.

Figure 2, a; plan orftop view of the same. i i I Similar letters ofreference indicate like parts. H p

This invention relates to a new and useful improvement in machinery for applying a glazing or size to fibrous substances, such as cotton wedding, etc., and is a modification of, and an improvement on, a machine for a similar purpose, for which Letters Patent were granted to me hearing. date January 12th, 1865, and reissued April 5th, 1864. e o

The improvement consists in a novel arrangement of the glazing or sizing roller with the heated metal cylinder, over which the glazed or sized web passes and isldried, as hereinafter fully shown and described, whereby the web, during the glazing or sizing process, is preserved from any undue tension or strain, and prevented from being torn, upturned, or-broken, even when formed of short or inferior fibre.

A represents a framing on which the shaft B of a cylinder =0 is fitted transversely; said-cylinder being of metal,,or having a metallic exterior, made as smooth as possible, and heated by steam passing within the cylinder, or by other suitable means. D is a trough fitted in the framing A parallel with the shaft B of thecylinder G,

and E is a roller which is fitted longitudinally in said trough, and is nearly in contact with the cylinder-C, or

quiteclose to itas close as may be-without actually being in contact. The troiigh D contains the glazing or size F, and the roller E is partly submerged in the same, asshownin fig. 1,. The arrows in fig. 1 indicate the direction in which the cylinder 0 and roller E rotate. G represents the web which passes over the roller-,1), and is sized or glazed by being in contact with said .roller, which, in consequence of rotating in the size in trough D, surfaces the lower or under side of the web which is in contact with the roller. This sized under surface is brought in contact with the cylinder 0, over which it passes, and is dried by the heat or warmth of G. In consequence of therollerE being quite close to the cylinder 0, as shown in fig. 1, it will be seen that said rollerp'erforros two important functions, to wit: it sizes.0r glazes the web, and also delivers the some directly upon the cylinder 0. The roller,'in consequence of being covered with the size, will causethe web to adhere to its upper part, but not with sufficient tenacity to prevent the cylinder C, in its rotation, from gently raising it from the roller at, the angle between the'roller andpylindcr, as will be understood by referring to fig. 1. The roller E, rotating in the trough 1), containing size, with the web to be surfaced or sized passing over it, is an old and well-known means for sizing webs of cotton wadding; but such device I has not been. used in connection with a heated cylinder, 0, for drying'the sized surface, the web having been dried by passing upon an endless apron or carrier, and conveyed through a heated compartment, with'the glazed )snrface uppermost, in order that the web may not adhere to the apron or carrier. This plan involves the necessity of the turning of the web after it leaves the roller E, and said web, in consequence, passes over rollers, ire order to be reversed, and if not composed of superior strong fibre, will be liable to tear or rupture under its own weight, and the strain or tension to which it is subjected. Hence, with the old machine superior and expensive fibre must be used; or,-at all events, such fibre mnst be mixed with that of an inferior quality in such a manner as to insure a requisite degree of strength to the web, and this is now done by leaving the edges or selvedges df the web composed of the superior quality, as it i's,most liable to tear or rupture at those parts.

By my improvement it will be seen that the web may be composed of quite short or uniform fibre, as it is not subjected to any strain or tension in passing over the roller E and cylinderC, and the device is rendered very simple in construction. l

I do not claim the heated cylinder G, for that is the same as the one used in my patented machine previ ously alluded to; neither do I claim the roller E and trough D, for they comprise an old and well-known sizedistributing device for the purpose set forth; but I do claim as new, 'and desire to secure b yIeetters Patent- The combination of the size-distributing roller E and the heated cylinder arranged relatively with each other to operate substantially in the manner as and for the purpose set forth.
